摘要:
利用1981-2010年气候统计资料,分析河池市暴雨洪涝灾害时间变化、空间分布特征;结合地形地貌、人口密度分布、社会经济状况等资料,利用GIS系统分析河池市暴雨洪涝灾害致灾因子的危险性、孕灾环境的敏感性、承灾体易损性与防灾抗灾能力,最后给出基于上述4个条件的暴雨洪涝灾害风险区划。结果表明,河池市暴雨洪涝灾害呈波动式增加趋势,年均暴雨日为4.7-7.6天,东部各县暴雨洪涝开始和结束时间都较西部早;暴雨洪涝灾害综合风险的高风险区在河池市南部,北部为暴雨洪涝灾害低风险区。
Abstract:
According to the statistical climate data of 1981-2010, spatial and temporal distribution characteristics of rainstorm floods in Hechi were analyzed; Combined with landform, population density, social economic conditions and other data, heavy-rain flood risk zoning based on hazards of disasterinducing factors, sensitivity of hazard inducing environment, vulnerability of hazard-affected body and ability of prevent and fight natural adversities is given by using GIS system. The results show that the hechi city rainstorm floods have experienced a fluctuant increase; and the numbers of annual average raining day is 4.7to7.6, the start and end time of rainstorm floods in eastern counties is earlier than that in western; High risk area of the heavy-rain flood disaster risk distributes in southern of Hechi while the northern part is mainly low risk area.
